RESUMO

Objective@#To understand the occurrence and predictive factors of depressive symptoms among multi ethnic middle school students in Yunnan Province, so as to provide a referential framework for schools to carry out targeted mental health education.@*Methods@#From October to December 2022, 8 500 first grade students from 23 middle schools were selected from 11 minority areas in Yunnan Province by cluster random sampling method. Demographic information and data relating to the students lifestyles were collected by questionnaire, and the Children s Depression Inventory (CDI) was used to evaluate depressive symptoms. Chi square test was performed to compare differences in the detection rate of depressive symptoms among first grade middle school students for univariate analysis. A decision tree model of depressive symptoms in middle school students was established by using the Chi squared automatic interaction detector (CHAID).@*Results@#The detection rate of depressive symptoms among first grade students from multi ethnic middle schools in Yunnan Province was 28.26%. The decision tree model of depressive symptoms was academic stress ( χ 2=469.08) at the first level, breakfast behaviors (low/moderate academic stress: χ 2=155.49; severe academic stress: χ 2=105.24) at the second level, and the number of close friends (low/moderate academic stress and consuming breakfast 0- 2 days weekly: χ 2=23.15; low/moderate academic stress and consuming breakfast 3-4 days weekly: χ 2=14.99; severe academic stress and consuming breakfast 0-2 days weekly: χ 2=29.26; severe academic stress and consuming breakfast 3-4 days weekly: χ 2=20.15), ethnicity ( χ 2=78.22) and drinking ( χ 2=50.36) at the third level ( P <0.01).@*Conclusions@#The study identifies academic stress, breakfast behaviors, number of close friends, drinking and ethnicity as predictive factors of depressive symptoms among multi ethnic middle school students in Yunnan Province. Schools should develop targeted strategies for preventing and managing depressive symptoms in middle school students, so as to reduce their occurrence.

RESUMO

Vitiligo disease makes patients generally exist anxiety,depression,excessive stress response and other psychological characteristics,and the psychological harm caused by disease is more difficult to deal with than the harm caused by the disease itself.Due to the particularity of disease itself,the psychological pressure of general patients is greater than other disease and the psychological problems are more serious.Therefore,when the vitiligo patients seek medical advice,we should pay attention to more respects for patients,protect the privacy of patients;strengthen the emotional reaction between doctors and patients;make good use of psychological function;and promote the establishment of a good doctor-patient relationship and realize the benign interaction of doctor-patient relationship to make the condition of vitiligo patient gradually improved,and finally return to health.

RESUMO

Objective To study the expressions of mucin (MUC) 1 and 2 in extramammary Paget's disease(EMPD) lesions. Methods Tissue specimens were obtained from the lesions of 19 patients with EMPD and normal skin of 19 human controls during cosmetic surgery. Streptavidin-perosidase (SP) technique was used to detect the expressions of MUC1 and MUC2 in these specimens. Results As haematoxylin-eosin (HE) staining showed, 3 cases were accompanied by poorly differentiated adenocarcinoma, 6 were invasive Paget's disease and 10 were intraepithelial EMPD. MUC1 was expressed in 2 cases accompanied by poorly differentiated adenocarcinoma, and in all the cases of invasive and intraepithelial EMPD; MUC2 was observed in all the cases of adenocarcinoma-complicated EMPD and invasive EMPD, but only in 2 of 10 cases of intraepithelial EMPD.Neither MUC1 nor MUC2 was observed in normal control specimens. A significant increase was observed in the expression of MUC1 in lesions of intraepithelial EMPD compared with invasive EMPD and adenocarcinoma-complicated EMPD (both P < 0.05), and in the expression of MUC2 in lesions of invasive EMPD and adenocarcinoma-complicated EMPD compared with intraepithelial EMPD (both P < 0.05). The expression of MUC1 was uncorrelated to that of MUC2 (r= -0.5, P> 0.05). Conclusions MUC1 is generally expressed in the lesions of EMPD, while MUC2 is expressed in those of adenocarcinoma-complicated EMPD and invasive EMPD.

RESUMO

To investigate the effects of ATRA, acitretin and tazarotene on the growth and apoptosis of human tongue squamous cell carcinoma cell line Tca8113. The effect of retinoids on growth of Tca8113 cells in vitro was examined by MTT assay and Trypan blue exclusion assay. Cell cycle analysis, early apoptosis analysis with double staining with Annexin V-FITC and PI, and active caspase-3 analysis with the staining of FITC-conjugated monoclonal rabbit anti-active caspase-3 antibody were made by flow cytometer. Streptavidin-biotin complex (SABC) immunocytochemical assays were employed for the detections of Bax/Bcl-2 proteins expressions. Our results showed that the retinoids inhibited growth of Tca8113 cells in a dose- and time-dependent manner with maximal inhibition 24 h after treatment of 10-5 mol/L. 10-5 mol/L retinoids altered cell cycle distribution of Tca8113 cells, revealing an increase in G0/G1-phase population, a decrease in S-phase population and the inhibition of G1/S switching. 10-5 mol/L retinoids significantly induced apoptosis of Tca8113 cells (all P<0.05), elevated the cells population with detectable active caspase-3 (P<0.05 for all), increased the number of cells forming Bax and decreased the number of cells forming Bcl-2 significantly (all P<0.05). Acitretin played a most prominent role among the retinoids. It is concluded that the inhibition of cell cycle progress of Tca8113 cells by ATRA, acitretin and tazarotene is one of the possible mechanisms for proliferation arrest of Tca8113 cells elicited by the retinoids. The retinoids mediate apoptosis in Tca8113 cells that may be caspase-dependent through mitochondria pathway. High concentration retinoids inhibit growth of Tca8113 cells in vitro by interfering with proliferation and inducing apoptosis of cells. Acitretin may be an alternative medicine for the prevention and treatment of tongue squamous cell carcinoma.

RESUMO

Many factors are involved in the ever tenser physician——,including the poor communication between doctors and patients,patients' zexcessive expection towards doctors,and the improper intervention from external factors such as the mass media,etc.To cope with the problems in current physician——patient relationship,medical institutes should strenghten the construction of medical ethics within their systems,and the"Third-party mediation mechanism"conducted in some areas can also be taken as effective measures to improve current physician-patient relationship.
